Examples

Examples are divided in 2 parts:

The first part are some simple client examples which can be copied and run directly. These examples show the basic functionality of the library.

The second part are more advanced examples, but in order to not duplicate code, this requires you to download the examples directory and run the examples in the directory.

Ready to run examples:

These examples are very basic examples, showing how a client can communicate with a server.

You need to modify the code to adapt it to your situation.

Simple asynchronous client

Simple synchronous client

Source: examples/simple_sync_client.py

../../examples/simple_sync_client.py

Client performance sync vs async

Source: examples/client_performance.py

../../examples/client_performance.py

Advanced examples

These examples are considered essential usage examples, and are guaranteed to work, because they are tested automatilly with each dev branch commit using CI.

Tip

The examples needs to be run from within the examples directory, unless you modify them. Most examples use helper.py and client.py or server_.py. This is done to avoid maintaining the same code in multiple files.
